� F. ABSORPTION WIDTH Absorption ratio: 2 <br /> 1, Absorption width equals absorption ratio times rock layer width <br /> 2.00 x 10.0 ft = 20A ft <br /> G. MOUND SLOPE WIDTH 8�LENGTH(Greater than 19G) <br /> 1. Downslope absorption width=absorption width minus rock layer width <br /> 20.0 feet - 10.0 feet= 10.0 ft <br /> 2. Calculate mound size � <br /> UPSLOPE � � <br /> a.Depth of clean sand at upslope edge of rodc layer=3 feet minus distance to restricting layer(C1) <br /> 3.0 ft - 2,0 ft= 1.0 ft <br /> b.Mound height at the upslope edge of rock layer=depth of clean sand for separation(G2a) <br /> at upslope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1 ft+1ft+1 ft= 3.0 ft <br /> c.Upslope berm multiplier based on land slope(see figure D-34) <br /> Selected berm multiplier: 2.78 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.78 x 3.0 ft = 10.0 ft <br /> DOWNSLOPE <br /> e.Drop in elevation=rock fayer width(D2)times percent landslope(C5)/100 <br /> 10.0 ft x 11.0 % /100= 1.1 ft <br /> f.Downslope mound height=depth of clean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 1.1 ft + 3.0 ft= 4.1 ft <br /> g.Downslope berm muitiplier based on percent land slope(see Figure D-34 <br /> Selected bertn multiplier: 5.88 <br /> h.Downslope width=downslope multiplier(G2g)times downslope mound height(G2fl <br /> 5.88 x 4.1 = 24.0 ft <br /> i.Select greater of G1 and G2h as the downslope width 24.0 ft <br /> j.Totai mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 10.0 ft+ 10.0 ft+ 24.0 ft= 44.0 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length(D3)plus upslope width(G2d) <br /> 10,0 ft + 38.0 ft+ 10.0 ft= 58.0 ft <br /> Final Dimensions (slope>1% 44.0 ft x 58.0 ft <br /> 1 hereby rtify that all work has been completed in accordance with all applicable ordinances,rules&laws. <br /> (signatu�e) 810 (license#) 8/14l2006(date) <br /> Page 2 of 5 <br />
